British singer Adele, who was forced to cancel her much-anticipated North American tour after being diagnosed with laryngitis, has hit the stage again. She enthralled the crowd at the London's iTunes festival on July 7 with her powerful voice.

The “Rolling In The Deep" hitmaker showed no sign of voice problem at the iTunes festival. She put up a wonderful performance, belting out her hits like “Rolling In The Deep", “Chasing Pavements" and “Someone Like You".

However, she told the crowd that she is still abstaining from alcohol due to her voice problem. She was recently voted the Most Powerful person in the British music industry. She beat the likes of Simon Cowell, Jay-Z and Damon Albarm in the Music Power 100 poll conducted by the Guardian newspaper. Her album '21' topped the UK album charts for 16 weeks.
